To all whom t may concern:

Be it known that I, WILLIAM S. SNvnnR, a citizen of the United States,.and a resident of Nashville, in the county of Davidson and State of Tennessee, have invented cer' tain new and useful Improvements in Hy drants, of which the followingv is a specification.

My invention is an improvement in hydrants, and has for its object `to providea hydrant-whereinv the valve controlling the flow `of water is normally lspring closed, and is controlled to opening position by the action of the hose connection.

A further object is to provide a hydrant having drainage, and whereinv all of the parts may be removed for repair or inf spection, and wherein such parts .are protected from freezing.

In the drawings Figure 1 is a vertical section of the improved hydrant, l

Figs. 2- and 3 are sections on the lines 22, and ,3V-3, respectively ofjFig; 1,

lFigj/l'is a top f, plan view with the cover opened, y f

Fig. 5 `is, a perspective view of the hose connection, Y

- Fig. `6 is a similarview ofthe valve.

VIn thepresent embodimentof the inven V tion, .a suitable casing -1 is provided for housin the working parts ofthe hydrant,

and this casing which is adapted to be .in-

serted in the ground to a suitable depth has a top or head 2 which is provided `with a cover 3 hinged thereto for closing the top of the hydrant. p shapedfextension t is connected with the casing 1, and this extension houses the lelbow 5 whichconnects the hydrant with the water main. i As shown, this elbow has a marginal flange 6 at its outer end, which fits between the extension 4 and the bottom of the casing 1, and the casing has threaded engagement with an upstanding rib 7 on the flange. The elbow has a threaded stem 8, which extends through an opening in the bottom of the cup shaped extension, and is engaged by a nut 9 to secure the extension to the casing 1 and to theelbow.

The opening in the upper end of the elbow 5 is reduced and internally threaded, to receive a threaded nipple 10 on the lower end of a reduced connection 11, which con- At its lower end, ay cup.

Vso that the pins may pass nects the'elbow with the body 12 of the hydrant. An annular shoulder 13 is pro- "vided between the union and the nipple whichl engages the upper end of the elbow, and the upper -end of the union has an'upstanding flange 14 into which the .lower end of the body 12 `is threaded.

A partition 15 at the upper end of the union has a central opening, through which is slidable, the tubular valve 16-17. This valve consistsof two portions of unequal diameter, the portion 17 being of greatest diameter land having a port or ports 18 which when below the partition 15 permit the waterto flow into the valve and through the same to the hose.l

A coil spring 19 encircles the valve within the union, between an internal annular shoulder in Vthe union'and a nut 21 threadedV on the portion 16 ofthe valve. Above this nut and between the same and theannular shoulder between the portions 16 and 17 of the valve, there is arranged a pair of oppositely disposed .concave washers 22 and 23, and the under end ofthe opening through the. partition 15 is counter-bored to receive the upper face of the washer 22 whichl coperates with the counter-bore to seal the opening through the partition.

It` is the portion 17 of the valve which slides ,in the opening of the partition,y and the -coil spring will'normally hold the valve with the openings 18 above the partition, and with the opening through the partition sealed a'wvasher 22. The upper end `of the 'portion 17 of the valve is threaded into a tubular casing 245, which at its upper end has a cap 25 provided with a reamed opening 26. With this Vopening is adapted to engage the beveled lower 4end of one arm 27 of an elbow `-27-28. The other arm 28 of the elbow is adapted for engagement by a hose.

The arm 27 of the elbowv has a fixed collar 29 thereon, and this collar has oppositely extending pins 30 which are adapted to engage beneath an inwardly extending web 31 onan extension 32 from a catch 33 which is threaded onto the upper end of the body 12 of the hydrant. These webs are arc shaped, and are spaced apart at their ends between them and engage between the webs.

A washer 34.- encircles the body of the hydrant, within the bowl 2, forming a seal at the extension to bey placed over the elbow.V

' The extension 32 is polygonal in cross section in order that a wrench ma be engaged e therewith, andthe threads w ich connect the nipple l() with the elbow are left hand threads, all of the others being right hand. Thus when a wrench is engaged with the extension 32. the entire hydrant construetion including the union 11 may be detached from the elbow and removed from the casing for any purpose desired. The elbow 5 may also be removed when the hydrant isremoved.

The casing l protects the hydrant from dirt, forming an inclosing casing for the same and also )rotects it from freezing, i In use, when it is desired to provide water, the lid or cover 3 is raised, andthe arm 27 of the elbow 27-28 is thrust through the extension 32 and the cap 33, until the beveled lower end thereof engages the cap25. The elbow is now given a quarter turn, causing the pins-to engage beneath the `webs of the extension.

The inward thrusting of the arm 27 of the elbow .forces the valve it- 17, and the tubular casing 24 downward, bringing the openingflB below the vpartition '15. The water now ows'freely throu h the valve, the tubular casing 24, the el ow and the hose. When the elbow 27-28 is released,

the spring forces the valve upward, tightly sealing the hydrant. AnyV waste water within the body l2 of the hydrant may drain away through the openings 35, 36, and 37.VV

l. A hydrant, comprising a union for connection with the main, said union having at its upper end a transverse partition provided with a central opening, a tubular valve slid* able in the opening, and having lateral ports, a spring normally pressing the valve upward to bring the ports above the partition and toprevent the flow of water into and through the valve, theV lower end` of the valve being closed, an extension connected with the upper end of the valve and having a beveled seat at its upper end, a hose con- .nection having its end beveled to engage the seat, and a casing inclosing the. valve, `the spring, and the extension and havingan opening for receiving the' connection, said` opening and having a lateral port, a springv normally pressing the valve upward to bring the port above the partition to prevent the How of water through the valve, a casing inclosing the valve, a union for connection with'the valve, and an interlocking connec tion between'the union and theV easing for holding the valve open when the union is engaged with the valve, and an inclosing casing `for drain openings. f y

3. A hydrant comprising a union for connection with-y the main, and having at its upper end atransverse partition provided with an opening, a tubularV valve slidable in the opening and having a lateral port, a spring normally pressing the valve upward to bring the port above the partition to prevent the flow of water throughV the valve, a casing inclosing the valve, a union for. connection with'the'valve,*and an interlocking connection between the union andthe casing for holding the valve open when the unio is engaged with the valve.

4. In a hydrant, a valve for controlling the flow of thewater and movable longitudi nally of theV hydrant intoopen and closed position, a spring normally holding the valve` in outward closed position, anda union, said valve having means for engagementby the union to move the valve into open position', a casing'for the valve, and interlocking mechanism in connection with the casing and' the' union'for holdingftheV union with the valveopen.
